Comparison for ZEN and Fiji Stitching results

Hi,

I just tried to compare the ZEN stitching with the Fiji one, since Fiji
Stitching has some very nicefeatures, we are still missing ...

The test data set can be found here:

https://dl.dropboxusercontent.com/u/623476/Overview_10X_DAPI.czi

The problem is, that the Fiji stitching is "moving" some tiles to a position,
where they do not belong. And the result has empty tiles, while the original
CZI images does not have any empty tiles.

The original area is a rectangle, so the result must also be a rectangular tile
area (since this is knwon from the stage coordinates, since I use "Positions
from File" & "Defined by image Metadata"). But in Fiji the result looks
different --> see attachment.

It seems to me, that Fiji is moving some tiles, where is "not much to stitch"
to some XY position instead of leaving them at their original positions, when
the tile is rather "empty" (just an idea).

Do you have any idea, how solve this issue?

Sebi
